Yes, I do. I am 5'11" and 1.8m tall. I am 50. I prefer metric to imperial (OK, living on the continent I don't really have a choice).
Where metric really wins out is in fractions: 5.6cm, or 56mm, makes sense but 2⅜"? Screw that!
Oh, and temperatures. I'm even getting used to hot weather in Celcius, but when I was in the US during Winter and they were quoting temperatures in minus Fahrenheit, I was all 'W.T.F?' :?
